Comparing structural decomposition analysis and index

Energy Economics, 2003
To analyze and understand historical changes in economic, environmental, employment or other socio-economic indicators, it is useful to assess the driving forces or determinants that underlie these changes. Two techniques for decomposing indicator changes at the sector level are structural decomposition analysis (SDA) and index decomposition analysis ...

Domain decomposition in acoustic and structure–acoustic analysis

Computer Methods in Applied Mechanics and Engineering, 2001
Conclusion: This paper suggests a scheme for modal decomposition of interacting structure-fluid and fluid-fluid systems. A symmetric standard eigenvalue analysis is employed for interacting systems based on eigenvalue analysis conducted on subdomains.

Accounting for nitrogen in Denmark—a structural decomposition analysis

Ecological Economics, 1999
Abstract This paper examines the environmental-economic cycle for nitrogen in Denmark based on nitrogen input and output from different economic sectors. An input-output model is employed together with a nitrogen mass balance to apportion total nitrogen loading by final demand and estimate export and import of nitrogen from foreign trade. The changes

Structure-Preserving Sparse Decomposition for Facial Expression Analysis

IEEE Transactions on Image Processing, 2014
Although facial expressions can be decomposed in terms of action units (AUs) as suggested by the facial action coding system, there have been only a few attempts that recognize expression using AUs and their composition rules. In this paper, we propose a dictionary-based approach for facial expression analysis by decomposing expressions in terms of AUs.

Decomposition methods for structural reliability analysis

Probabilistic Engineering Mechanics, 2005
A new class of computational methods, referred to as decomposition methods, has been developed for predicting failure probability of structural and mechanical systems subject to random loads, material properties, and geometry. The methods involve a novel function decomposition that facilitates univariate and bivariate approximations of a general ...

Structural Analysis and Decomposition of Complex Systems

IFAC Proceedings Volumes, 1983
Abstract This paper deals with the application of hierarchical structural analysis to the decomposition and control of complex systems. The strength of the relationship between subsets of variables describing the systems is obtained by computation, using information theory concepts, among a set of experimental data. “Good decompositions” are obtained

Regression component decomposition in structural analysis

Communications in Statistics - Theory and Methods, 1991
A crucial problem in the Lisrel model remains that of finding necessary and sufficient conditions for the identification of the parameters. But even if the parameters in a particular model are identifiable, there remains an indeterminacy of the scores of the latent variables.

Multidimensional spectral analysis and the decomposition of ionospheric mode structures

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Because wave interference effects due to ionospheric multipath and undesired signals within the receiver bandwidth may cause large bearing estimation errors, it is necessary to resolve the constitutent wavefield incident upon an array of sensors. This paper considers the comparative performance of five multidimensional spectral analysis algorithms in ...

A Structural Decomposition Analysis of Global and NationalEnergy Intensity Trends

The Energy Journal, 2018
This paper analyses recent energy intensity trends for 40 major economies using a structural decomposition analysis. Our focus lies on the question whether improvements in energy intensity were caused by structural change towards a greener economy or by technological improvements.
